The correct answer is 3 because the testis is the male reproductive organ responsible for the production of sperm. Sperm production occurs in the seminiferous tubules, which are located within the testis. Therefore, option 3 is the correct label for the area where sperm formation occurs.

The correct answer is "Genotipe". In genetics, genotipe refers to the genetic makeup of an individual, which includes the combination of alleles for a particular trait. In this case, the curly hair trait can be represented by the symbols BB or Bb, indicating the presence of the allele for curly hair. Therefore, genotipe is the appropriate term to describe the symbols BB or Bb that represent the curly hair trait.

Gambar tersebut menunjukkan struktur ginjal, dan nomor 4 menunjukkan bagian ginjal yang berfungsi menyaring (filtrasi) darah.

The given answer, 9 : 3 : 3 : 1, represents the phenotypic ratio of the offspring resulting from the cross between two individuals with two different traits. This ratio suggests that one phenotype appears in the offspring nine times, while the other phenotype appears three times, and the remaining two phenotypes each appear once. This indicates that one of the traits is dominant and the other is recessive, with the dominant trait being expressed more frequently in the offspring.

Dalam soal ini, terdapat dua orang yang memiliki gaya dorong 200 N dan 100 N. Untuk membantu mereka mendorong mobil dengan gaya gesekan 320 N, kita perlu mencari kombinasi gaya dorong yang totalnya dapat menghasilkan usaha sebesar 7.000 J saat mobil berpindah sejauh 10 m. Dalam tabel yang diberikan, hanya kombinasi gaya dorong dari Soleh, Yanto, dan Asep yang memiliki total gaya dorong yang cukup besar untuk mencapai usaha yang diinginkan. Oleh karena itu, jawaban yang tepat adalah Soleh, Yanto, dan Asep.

Massa jenis is a derived quantity that is derived from the fundamental quantities of mass and length. It is defined as the mass per unit volume of a substance. The other options, such as kecepatan (velocity), percepatan (acceleration), and energi potensial (potential energy), are not directly derived from mass and length.

The correct answer is (2) dan (4). This is because in the table, the substances with numbers (2) and (4) have a pH value less than 7, indicating that they are acidic solutions.

The correct answer is Q because the question is asking for the letter that represents the part of the image that contains the organ of Corti. By looking at the image, we can see that the organ of Corti is located in the part represented by the letter Q.

The correct answer is A because in the given table, option A is the only one that represents a gas. The other options (B, C, and D) may represent solids or liquids, but not gases.

Asetilkolin adalah senyawa kimia yang berfungsi sebagai transmitor (pengirim) impuls pada sinapsis. Ini berarti bahwa asetilkolin bertanggung jawab untuk mengirimkan sinyal atau impuls dari satu neuron ke neuron lainnya melalui sinapsis.

Perkembangbiakan secara kawin adalah proses reproduksi yang melibatkan perpaduan materi genetik dari dua individu yang berbeda. Dalam proses ini, gamet dari individu jantan dan betina bergabung untuk membentuk individu baru yang memiliki kombinasi genetik yang berbeda dari kedua induknya. Oleh karena itu, sifat individu baru yang terbentuk akan berbeda dengan sifat induknya.

Gerak refleks adalah gerakan yang terjadi secara otomatis sebagai respons terhadap rangsangan tertentu. Sistem saraf pusat terletak di sumsum tulang belakang karena gerakan refleks ini dikendalikan oleh refleks spinal yang terjadi di sumsum tulang belakang. Gerakan sadar, di sisi lain, melibatkan proses pemikiran dan kesadaran yang lebih kompleks. Sistem saraf pusat untuk gerakan sadar terletak di otak, khususnya di medula oblongata yang berperan penting dalam pengaturan gerakan sadar.

Balok yang memiliki percepatan paling besar adalah balok yang mengalami gaya terbesar. Dalam fisika, gaya yang bekerja pada suatu benda dapat dihitung dengan rumus F = m x a, di mana F adalah gaya, m adalah massa, dan a adalah percepatan. Jika massa balok-balok tersebut sama, maka balok yang memiliki gaya terbesar akan memiliki percepatan yang paling besar pula. Oleh karena itu, balok yang memiliki percepatan paling besar adalah balok yang mengalami gaya terbesar di antara balok-balok tersebut.

The correct answer is (1) and (3). The explanation for this answer is not available.

Penderita rabun jauh atau miopi memiliki lensa mata yang terlalu cembung. Kondisi ini menyebabkan cahaya yang masuk ke mata penderita divergen atau menyebar, sehingga fokusnya terjadi sebelum mencapai retina. Dengan menggunakan kacamata berlensa negatif yang lebih cembung, cahaya dapat ditekuk lebih jauh sehingga fokusnya jatuh tepat di retina, memperbaiki penglihatan penderita.

The correct answer is 3:4. When Budi releases the ball from a height of 100 m, the ball will have potential energy equal to its mass (100g) multiplied by the acceleration due to gravity (9.8 m/s^2) multiplied by the height (100 m). The maximum potential energy is therefore 100g * 9.8 m/s^2 * 100 m. As the ball falls, it will convert this potential energy into kinetic energy. The maximum kinetic energy is equal to half the mass (100g) multiplied by the square of the velocity at the bottom of the fall. Since the height is divided into quarters, the ball will have converted 3/4 of its potential energy into kinetic energy, resulting in a ratio of 3:4.

The data that shows a physical change and a chemical change in order are 1 and 3. In statement 1, chocolate melting when heated is a physical change because it does not involve a change in the chemical composition of the substance. In statement 3, the neutralization of an acid by adding a base is a chemical change because it involves a reaction that results in the formation of new substances. Therefore, both statements 1 and 3 represent different types of changes, one physical and one chemical.

When the load is shifted 10 cm towards the pivot without changing the magnitude of the force, the lever arm of the force increases. According to the principle of moments, the moment of the force is equal to the moment of the load. Since the force and load are balanced, the moment of the force must remain the same. To keep the moments equal, the lever arm of the force must increase. Therefore, the force must be shifted 50 cm towards the pivot to maintain balance.

The correct answer is 2 and 3. Amoeba dividing itself is a form of adaptation as it allows the organism to reproduce and increase its population. Lizards, including cicak, have the ability to detach their tails as a defense mechanism when they feel threatened. This adaptation helps them escape from predators and survive in their environment. Therefore, both activities demonstrate characteristics of adaptation.
